Ryne Sandberg drove in three runs and reliever Jim Bullinger won for the first time since Aug. 30 as host Chicago finished the first sweep of Florida.
Sandberg's sixth-inning double off Luis Aquino (4-4) broke a 2-2 tie and drove in Jose Vizcaino, who also scored on Sandberg's single in the fourth. Sandberg added a run-scoring groundout in the seventh, making the score 6-3.
Bullinger (1-0), one of three Triple-A pitchers called up Tuesday to replace three injured starters, relieved Jose Bautista in the sixth. He went 1 innings, allowing no hits and two walks before being relieved by Paul Assenmacher. Randy Myers pitched the ninth for his major-league-leading 21st save. Bautista, who made his first start since Sept. 17, 1989, allowed two runs on five hits as the Cubs reached the .500 mark for the 17th time this season.
Florida's Mitch Lyden became the 67th major-leaguer and 36th National Leaguer to hit a homer in his first at-bat. He sent an 0-and-1 pitch from Bautista onto Waveland Avenue with one out in the second, giving Florida a 2-0 lead.
